1. A fan device, comprising:
an impeller; a motor for driving rotation of the impeller; a fan frame substantially shaped as a rectangular solid, wherein the fan frame comprises:
an airflow inlet plate in which an airflow inlet is formed;an airflow outlet plate in which an airflow outlet is formed, wherein the airflow inlet plate and the airflow outlet plate are disposed in parallel;four lateral plates, each being disposed on each of four edges of the airflow inlet plate and the airflow outlet plate; anda channel wall defining an axial-flow channel for accommodating the impeller and the motor, wherein a receptacle, which is an internal space within the fan frame, is defined by the airflow inlet plate, the airflow outlet plate, the channel wall and three of the four lateral plates; and a circuit board accommodated within the receptacle, wherein one of the four lateral plates is a covering member detachably fixed to two adjacent lateral plates, the airflow inlet plate and the airflow outlet plate to provide an access to the receptacle, wherein the covering member is substantially U-shaped, wherein the covering member comprises a bottom plate and two flank plates, wherein corresponding to the two adjacent lateral plates, the tips of the flank plates are formed as stepped structures, and wherein the stepped structures are engaged with the two adjacent lateral plates which define the receptacle of the fan frame. |
